# airMAX M devices: cross-site request forgery lets lured users change settings

airMAX M wireless devices have a cross-site request forgery flaw: a malicious page visited by a logged-in administrator can send requests that change configuration. An attacker can also use it to cause a denial of service on the device.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Identify airMAX M devices on the network and note the firmware version shown in the device web interface
- unknown

## Fix

- Update airMAX M devices to a fixed firmware version (unknown; the sources do not name it)
- Until patched, log out of device web interfaces after use and avoid browsing untrusted sites while logged in

## Timeline

- 2026-10-27T01:34:33+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-116839

## From the sources

A malicious actor who lures an authenticated user to a malicious page could exploit a Cross-Site Request Forgery (CSRF) vulnerability found in airMAX M devices to make unauthorized changes and execute a Denial of Service (DoS) attack on the device.
